Yes. It's almost a must with a full front but in any case it will hold the dust vortex back. However do know you will still get some in through the door ways. Not much with a half-shield though....it will blow it out pretty well.

Yes it helps a lot, we have a half windshield on ours and before we put rear glass on the dust was terrible, with rear glass very little dust.Of you don’t use a rear glass you’re better off without a front glass.
